The food: fine but not amazing. The calamari was lightly breaded, giving it a subtle flavor and crunchy texture. My almond crusted trout was buttery and just barely underseasoned. The accompanying orzo was dry but tasty. My girlfriend's fish and chips were too salty -- we couldn't finish the fish.
The service: our waitress was nice and checked in frequently, but the food took a long time.
The ambiance: quiet, peaceful, about what you'd expect of a McCormick and Schmick's.
Overall, a decent dining experience, but I wouldn't go back if I were to revisit Pittsburgh.
